Thats my database right now, and i have insert 25.034 records at the moment. one record has id,number,date,time and 20 numbers (No1-No20) with numbers between 1-80 with no duplicates of-course on each record.

You may easy understand that this is some lottery game records. so far so good.

what i want to do? easy to say but i don't even know if is possible.....

My point is to check IF there is some duplicate records between fields (No1 and No20) and check IF there is some probability the "lottery system" to make some "loops" and IF it does... i just want to see the periodically of looping.
